Ian Williams has dealt with several injuries, but if he can remain healthy, he would likely be the 49ers starting nose tackle. Former 49ers defensive tackle Justin Smith had big praise for Williams.
One of many San Francisco 49ers position competitions to watch this summer will be at nose tackle. Ian Williams, Glenn Dorsey and Quinton Dial all have gotten extensive playing time at the position over the last two years. Dorsey spent most of 2013 starting at nose tackle, Williams started 2014 in the starting role, and Dial took over midway through the season after Williams suffered a leg injury.
